Well, I can't say that the prophecy was entirely clear. I don't know precisely what Londo's two blown chances were, although the events of "The Coming of Shadows" are probably in there. But G'Kar's eye is pretty clear, especially when you factor in the message of "The Very Long Night of Londo Mollari." From there on out, my interpretation rests on my assessment of Londo's character and of how a story ought to work. Many people don't agree with my interpretation.
